a400p in ESXi

Hello, are these cards supposed to work in eg esxi 6.7?
I had one working in early esxi ie esxi4.0
And the card works fine on the pc when booted conventionally (freepbx running off a usb drive)
But there is no dial tone on the FXS and I'm unable to dial out on the FXO when esxi 6.7 runs off from a usb drive on the same pc, after a fresh install on an esxi virtual machine, yet all the commands seem to work eg:
[root@freepbx ~]# systemctl status dahdi.service
